STORM SENTINEL

Hold the rooftop. Read the lane. Counter before impact.

STORM SENTINEL is a 90-second three-lane air-defense action game. Missiles descend toward the left, center, or right rooftop zone. Wait until the signal enters the counter window, then press the matching lane before it crosses the strike line.

2. Wait while a missile shows “WAIT.”

5. Survive all four storm stages and protect the relay.
